Contact service life of the main contacts
The characteristic curves show the contact endurance of the contactors when switching
capacitive loads (AC-6b) depending on the reactive power Q
N
and rated operational voltage.
The rated operational current I
e
complies with utilization category AC-6b (breaking 1.35 times
the rated operational current) and is intended for a contact endurance of at least 150 000 to
200 000 operating cycles.
